# Modulator - Generate skeleton modules.
|
|
#
|
|
# The user fills out some forms with information about what the module
|
|
# should support (methods, objects), names of these things, prefixes to
|
|
# use for C code, whether the objects should also support access as numbers,
|
|
# etc etc etc.
|
|
# When the user presses 'Generate code' we generate a complete skeleton
|
|
# module in C.
|
|
#
|
|
# Alternatively, the selections made can be save to a python sourcefile and
|
|
# this sourcefile can be passed on the command line (resulting in the same
|
|
# skeleton C code).
